The twins came to town one afternoon to celebrate their eighteenth birthday with me. The actual day was a week before, but I'm just their uncle, so understandably, I have to wait my turn. They came with their cousin, Tanya. She's the same age, and the three of them have always been best friends. I took the whole gang to a great little place made of old bricks, hidden down an ordinary-looking garden alleyway. They make their own wine there, and they have the best stone-oven pizza you've ever tasted. We stayed for lattes and had an early dinner. We talked about the family and how the twins, both Benn and Gabby, had gotten scholarships. The waiter never made us feel rushed, and somewhere in the background, lively violins played on an old record player.
We walked back to my place, just a few blocks, the whole way lit with bright streetlights and glowing neon signs. The twins and Tanya slouched on my sofa; everyone was stuffed with dinner, but we had cake anyways, just a few bites each and only for tradition. After presents, I sang Happy Birthday for Benn and Gabby in my best baritone voice, but by then it was late. The girls and my nephew seemed tired, so I pulled out the spare blankets and all the extra pillows. As they went off to the spare room, they hollered "Goodnight," and I wished them the same.
I watched the news for a while, something about how they'd just invented the first artificial heart, but the place was a mess—I couldn't just sit there. I got to my feet and started cleaning up. It didn't last long. The wine from the restaurant was still swimming in my head. Dizzy, I turned out the lights and stumbled down the hall, feeling my way as I went. As I passed the spare room, I heard the three of them in there, speaking quietly, like they didn't want me to hear.
"I don't know if we should do this," Benn commented. "But it is kind of hot."
His cousin, unbelievably the very same girl he'd grown up with, replied, "You don't have to, but I've always wondered what twins would look like if they..."
Leaning in closer, I carefully touched my ear against the wood. "That's why you're trying to convince us!" Benn deduced with a muffled laugh. "You're like a dirty old man, you know that?"
"We could try it," his sister suggested. "If you want to..." I was surprised by her directness. Between the three of them, Gabby had always been the quiet one. Just then, I realized I'd been pressing my ear against the door a little too hard. I began to pull back to let some pressure off the creaky wood panel, but a groan escaped from the doorframe, and my niece called out in a worried voice, "Uncle Drake, is that you?" I heard them start tussling around like they were hiding a body. I wasn't really thinking. My brain was spinning, confused, or maybe I wanted to see. Whatever it was, I threw the door open, and there they were, all three of them, naked on the bed.
The girls screeched, shouting as I stood in the doorway, frozen in shock. They raced to cover themselves, but it was too late. They'd been on top of the covers, their legs spread wide, everything exposed. Benn had managed to retreat behind a pillow, but he'd also been revealed. I'd seen his erection poking out from his dark patch of tidy pubic hair. I'd seen how they'd all been more than close enough to touch.
They were panicking and embarrassed enough to make their eyes bulge, so I told them all to take a deep breath and relax. I sat on the edge of the bed and said, "It's about time I explained something to the three of you." My nephew looked like he was about to throw up, but at least the girls had gotten themselves down to a whimper. They stared at me like they were expecting to be thrown in jail and disowned like I'd forgotten we were family. "What you've done—" I began.
"Please don't be angry," Gabby interrupted. She pointed to her brother, a bedsheet hanging loosely off her arm. "It wasn't his fault," she cried. "He went to the bathroom, and when he got back, he caught us fooling around."
"I encouraged them," Benn admitted, his cheeks turning candy-apple red. "I guess we got carried away."
"You're not going to rat us out, are you?" Tanya asked. Her blonde hair fell over her cleavage, and for a second, despite everything, my Benn's eyes lingered there.
"Absolutely not," I told them reassuringly. "And like I was going to say, what you've done is perfectly okay."
Shocked, they stared at me. "What?" both my nieces asked at the same time.
"It's fine with me," I told them. "Everyone has secrets. Everyone's done things they keep hidden."
"What kinds of things?" Benn blurted out.
I sighed reluctantly. "Well... to be honest, me and your mom did certain things when we were younger. So I'm not judging you. You're all adults. You can make your own decisions." They were silent, but I could tell how relieved they were. "And," I stressed, "what I told you about your mom and I stays between us, just like this whole situation." They readily agreed, all of us bound by the weight of each other's sins. We had to get up early in the morning. I reminded everyone it was getting late and told them to put this behind them and go to bed. I told them I loved them, then I stood up and left the room.
I didn't hesitate to do what needed to be done. I went straight to the washroom and locked myself in. I dropped my pants to my ankles, grabbed my dick, and thought back to my nephew staring at Tanya's boobs even as he believed he was in the worst trouble of his life. I thought of the three of them on the bed, playing their forbidden games. If I'd been five minutes later, I knew I would have caught them screwing. I only needed to pull on my dick a few times, and the idea pushed me over the edge. Warm gulps of fluid rose up my shaft and flowed over my fingers, falling to the floor in eager dribbles. I couldn't even see the room around me, only fantasies of my nephew bouncing happily between his twin sister's legs.
When my balls were drained enough for me to start thinking again, I realized how angry my sister would be if she ever found out I'd told them about what we'd done when we were younger. At that moment, I'd thought my nieces and nephew needed to hear the truth. I hoped she'd understand if she ever found out. Suddenly, it occurred to me that it might have been a bad idea to leave the three of them alone together. As I made my way back into the hall and headed towards the spare room again, I lied to myself about needing to make sure they weren't still trying to do something wrong. This time, I was much more careful when I put my ear against the wood and listened.
"Don't. What if he comes back?" one of the girls whispered.
